'Fig. 7 is an enlarged fragmentary detail of the modification shown inFig. 4 and is a partial section taken along the line l'! of Fig. 4.

Fig. 13 is a side view, partly broken away, show- I ing the workingparts in its advanced cutting position.

Fig. 14 is a similar view, partly broken away and shows another positionof the operating parts.

Referring in detail to the parts, II designates a supporting frameformed with an inclined side member I2 having a recessed portion whichforms a pocket I3 within which a circular knife or cutter I 4 isrotatably mounted. Lugs I5 and It are formed upon the base of saidsupporting frame II to which the lower ends I? and I8 of a hopper jaw I9are pivotally attached. An operating arm having a handle 2| and legs 22and-23 is attached against the under side of said hopper jaw I9 and isheld in place by means of a rivet 24 formed upon the leg 23 of the saidoperating arm 20. The said rivet '24 is adapted to engage within acorresponding, orifice 25 in the leg I8 of the said hopper jaw I9. Asecond rivet 26 formed upon the leg I! of the said hopper jaw I9 engagethrough an orifice 21 in the leg 22 of the said operating arm 29. (Figs.8 and 11.)

The hopper legs I 'I and I8 are each formed with studs or bosses 21 andI8 respectively which are flattened along part of their peripheries asat 29 and 39 and are adapted to engage the legs 22 and 23 of the saidoperating arm 29. The said. flattened portions of the bosses, togetherwith the rivets 24 and 26 coact to hold the said operating arm securelyupon the hopper jaw I9. The said hopper jaw I 9 and its connectedoperating arm 29 are adapted to oscillate as a single unit about thepivotal connections I5 and I6. A pin 3 Ibeing employed to complete theconnection.

A second hopper jaw 32 having legs 33 and 34 is pivotally attached tothe legs I I and I8 respectively by means of a pin 35 around which aspirally wound spring 36 is mounted. The said spring ha adownwardlyextending arm 3! the end of which engages a slot 38 formed in a webformation 38' which unites the two said legs I! and I8 of the hopper jawI9. The opposite end of the spiral spring 36 has an upwardly turned arm39, the upper end of which is turned out at a right angle 40, to engagein a slot 4! (Figs. 4 and 9) formed in a hopper jaw 32. The said spiralspring 35 exerts a force between the hopper jaws I9 and 32 whichtends tobring them normally together and hold a product to be cut by therotating knife. The dot-dash lines in Figs. 10, 13 and 14 indicate afood produce which is to be sliced. 1

The angular end 49 of the spiral spring 35 is adapted to act as a bumperand limit the retractive movement of said hopper jaw 32. This limitationof movement is accomplished by the contact of the spring with a lug 42formed upon an arcuate flange 43 upon the frame I I. A gauge plate 44 isadapted to rest upon the said arcuate flange 43 and is adjustedrelatively with the rotating knife, by means of a four point helicalmechanism acuated by means of a hand knob 45 (Fig. 11) which engage acylindrical member 46, and enables full adjustment of the gauge plate byone quarter turn of the knob. The said cylindrical member 45 isrotatably mounted within a cup shaped portion 41 of the frame II and isrotatable therein. The inner edge of said cylindrical member is formedwith four helical surfaces 48 which contact complementary helicalsurfaces 49 formed upon an annular flange 50 in turn integrally formedupon the gauge plate 44. A spring 5! is adapted to hold the partstogether as clearly shown in Fig. 11, the spring 'being assembled intorsion to oppose the torsional component of the lineal spring force,due to the angularity of the helical surfaces. The hand. knob 45 iskeyed to the said cylindrical member 46 by means of pins 52 which engagein grooves 53. As shown in Fig. 11, the gauge plate 44 is set to cut aslice of minimum thickness. By turning the knob 45, the said gauge platemay be moved outwardly until the opposing helical surfaces are broughtclosely together at which point a slice of maximum thickness may be cutby the rotatingknife I4.

The knife and its associated drive mechanism mountings will be bestunderstood by the following description considered in connection withthe illustrations in Figs. 5, 6, l0 and 12. A boss or stud 54, having acentral bore 55, i shown in Figs. 6 and 12 and is formed in the pocketI3 of the frame II. Within the said bore 55, there is a bushing 56 andwithin the bushing is an internally threaded tubular member 51 to whichthe saidknife I4 is attached by means of the counter-sunk screw 58. Thesaid tubular member5'! is held upon the boss 54 by means of a screw 59and interposed washer 69. Rotatably mounted over the said tubular memberis a ratchet member GI having pawl elements EZheId in recesses orpockets 53 (Fig. 5). The ratchet member BI is provided with pins 64 bymeans of which the said ratchet is tied to the knife Mas clearly shownin Figs. 6, 10 and 12. The said ratchet SI is given rotary movement bymeans of a gear 65 having internal ratchet teeth with which the pawls BIengage. A flat .V-shaped spring 61 being employed to keep the said.pawls rfiigrmally in contact with the said ratchet teeth The said gear65 is activated or rotated by means of a rackIiS which engages'the gear65 and is held in alinement therewith by the idler or guide pulley 69(Figs. 10 and 12). When the ,rack 68 moves in the direction indicated bythe arrows X, (Figs. 5 and 10), the gear 65 and its associated ratchet'6! and knife I4 will. rotate in the direction indicated by the arrowsXf. When the rack 68 is retracted or moves in the opposite direction,the gear 65 will turn in a reverse direction to that above indicatedwhile the knife I4 will continue in its original rotary movement or cometo a stop.

Reciprocal movement is given to the rack 68 through its attachment at IDor I I, which attachment is fixed by the reciprocating pin I2 or 13clearly shown in Fig. 11 wherein the pin I3 is shown in engagement withthe rack 68 at II, the pin 12 being retracted by a rocker arm I4 pivotedat I5 tothe Web 38'. Obviously, withthis rocker arm connection, when thepin I3 is pushed into action the pin I2 moves out of action asindicated. When the pin I3 is pushed in and connection is made at II,between the rack 68 and hopper jaw I9 the relative position of the saidrack is as shown in Figs. 10 and 13. Fig. 10 shows the retractedposition of the operating parts and Fig. 13 shows the position of theoperating parts at the end of the forward or cutting movement. Theconnection of the rack 68 with the hopper jaw at H as just describedimparts a high speed rotation to the knife Hi. When, however, a slowerspeed of rotation to the knife is desired, the parts are retracted untilthe rack 68 rests in the stop 16 as at 11. When the operating parts arein the position just described, the pin 12 is pushed in to make aconnection between the rack 68 and hopper jaw l9 at 18 at the same timedisengaging the said rack and hopper jaw at H. With this last namedconnection of the rack and the hopper jaw the operating parts, when theoperating arm 20 has been moved forward, assume the position shown inFig. 14. This arrangement imparts a slow speed to the cutting knife 14and is desirable for slicing certain types of products. If desired thepin 12 may be shortened so that it does not connect to the rack 68 whenpushed in, thus allowing the said rack and the knife M to remainstationary when the operating arm is moved forward. In which case thepin 12 serves only to cause retraction of pin 13.

To prevent the accidental displacement of the pins 12, 13, the pin 72 isformed with annular grooves 19 and 88 which engage the lower leg 31 ofthe said spring 36.

In Figs. 4 and 7 there is shown a modified form which dispenses with therack 68 and driving gear 65. In this embodiment the gear 65 is replacedby a cylindrical member or drum 8| which rotates freely about theratchet member BI and has internal ratchet teeth similar to the teeth 66of the gear 65. A spiral spring 82 is attached at one end to the saiddrum 8! as at 83 (Fig. 4) and at its outer end is attached to a pin 84upon a lug 85 which is formed upon the stud 54. A wire, flexible cableor cord 86 is wound over the said drum at one end and at its other endis attached to a pin 81 upon the leg [8 of the hopper jaw l9. The saidcord 86 passes around an idler or guide pulley 88 which is rotatablymounted upon a boss formed upon the frame I l.

Suitable markings 89 may be provided upon the cup shaped portion 41 onthe frame I l to indicate various positions or settings of the gaugeplate 44 and a setting mark 90 may be provided upon the knob 45 to alinewith the markings 89 as the knob is turned.

A portion of the wall of the pocket I3 is cut away as at 9| (Fig. 2) toallow the slices, as they are cut from the food product in the hopper,to leave same and fall upon a shelf 92 from where they are discharged ortaken from the machine.

A slideable plate 93 may be suspended from the upper edge of the saidfixed hopper jaw I9 by means of a hooked end 94 and affords a meanswhereby small end sections of food products may be fed for slicing.

I claim:

1. A manually operated slicing machine for cutting slices from foodproducts, comprising a base and supporting member, a circular knife r0-tatably mounted thereon, an operating arm mounted upon said base andsupporting member and reciprocally movable thereon, a hopper having afixed and a movable jaw mounted upon said operating arm, the said hopperbeing adapted to hold a food product and the said movable jawcoordinating with the fixed jaw adapted to hold the said food product inplace, a rack pivotally attached at one end to the said fixed jaw, agear rotatable upon the frame and activated by the said rack, a pawl andratchet upon the said rotatably mounted knife coordinating with saidgear and rack to rotate the said knife, a spring means engaging betweenthe said fixed hopper jaw and movable hopper jaw adapted to hold themovable hopper jaw in gripping contact with a food product in saidhopper and a hand hold upon the said reciprocally mounted operating armto move same to bring the food product into slicing contact with thesaid rotating knife.
